Hi João,

that is exactly the way it is. PTLsim currently supports SMTs only, 
this means that all decoded micro-ops end up in the same ROB.
That one and the multiple units are executed sequentially.

A good starting point is OutOfOrderCore::runcycle(), ooocore.cpp, 
lines 316 to 596.

You can see the iteration through the treads' frontends there.

Kind regards,
